摘要: Novel corrugated horn have been modelled, manufactured and measured which give low-sidelobe patterns required by CMB Anisotropy experiments. These horns a Back-to-Back structure with mode filtering at their centres. They are to axial symmetric patterns, profiled reduce length, Gaussian flare entrance apertures further suppress sidelobes -40dB. Modelling experimental results show excellent agreement well below 50 dB.
